"This column constantly provides excellent separation efficiency given the nature of the complicated matrices I am working with.
Post sales communication has been helpful and resources are easy to find.
I will continue to use these columns. Very happy with the performance."

"These columns are good but they do not last long and require much care, they are difficult to regenerate.
The reproducibility is not the best depending on the matrix that is going through it.
I recommend them but only for specific functions and matrices.
